Indeed. I first encountered the "declaration of independence of cyberspace" a few years after it was written, and at the time I was immediately reminded of the Full Metal Jacket quote that goes something like "you can give your heart to Jesus but your ass belongs to the Marine Corps!"

That is to say the Declaration is pure cringe. The idea that cyberspace could become sovereign unto itself is patently absurd: The user's ass belongs to whichever country they inhabit.
